Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Jetty's jetty-http package (org.eclipse.jetty:jetty-http) versions 9.4.0 through 9.4.58, 10.0.0 through 10.0.26, 11.0.0 through 11.0.26, 12.0.0 before 12.0.31, and 12.1.0 before 12.1.5 parse some invalid or unusual URIs differently than other common parsers. An attacker can craft such a URI to bypass a component that filters URIs, such as a blocklist, or to reveal implementation details. Upgrade to 12.0.31 or 12.1.5; the source lists no workarounds, and the 9.4, 10.0 and 11.0 lines are end-of-life.
